Drug resistance profiles of Mycobacterium tuberculosis isolates to first line anti-tuberculous drugs: A five years study.

Background: Drug resistance is a major problem in the treatment of tuberculosis (TB). An estimate of drug resistance is extremely important in the epidemiology and control of TB. However, an assessment of the magnitude of drug resistance in TB is not very well described globally and data remains scantier for India.

A clinical and mycological study of onychomycosis in HIV infection.

Background: Onychomycosis is one of the early manifestations of HIV infection with a prevalence of 15-40%. Multiple nail involvement, isolation of both common and rare species and resistance to treatment are the characteristics of onychomycosis in HIV.

Aim: To study the epidemiology, clinical manifestations of onychomycosis in HIV-infected individuals and to identify the various causative fungi microbiologically.

A Survey of Clinical Isolates of Neisseria Gonorrhoeae For Betalactamase Producers.

Strains of Neisseria gonorrhoeae isolated from smear-positive male patients suffering from acute gonococcal urethritis were studied. Their identity was confirmed on the basis of morphology, oxidase reaction, fermentation of glucose only and failure to grow on nutrient agar. A total of 100 such isolates were, tested for beta-lactamase production by use of nitrocefin.
